Remember to means you do not forget an action you need to do later: Remember to lock the door. Remember doing means you have a memory of an action that already happened: I remember locking the door. The difference is about time: one points to a future or required action, and the other points to a past memory.
The Main Difference Between Remember To And Remember Doing
Use remember to + base verb when someone needs to do something. The remembering happens before the action.
Use remember + verb-ing when someone has a memory of doing something. The action happened before the remembering.
A simple test: if the action is still a task, use remember to do. If the action is already part of someone’s memory, use remember doing.
Remember To Do: Meaning And Use
Remember to do something means “do not forget to do it.” It often appears in reminders, instructions, advice, warnings, and daily tasks.
The structure is:
remember to + base verb
- Remember to call your mother.
- Remember to bring your passport.
- Remember to save the file before closing the program.
- Please remember to send the report today.
In each sentence, the action has not happened yet at the moment of the reminder. The speaker wants the listener to do the action later.

Remember Doing: Meaning And Use
Remember doing something means you can recall an action, event, or experience from the past. The action already happened, and now it exists as a memory.
The structure is:
remember + verb-ing
- I remember meeting her in London.
- He remembers locking the door.
- Do you remember visiting this museum?

In these examples, the speaker is not giving a reminder. The speaker is talking about a past action that they can still recall.

Remember To Vs Remember Doing In A Table
| Phrase | Meaning | Time Focus | Example |
|---|---|---|---|
| Remember to do | Do not forget to do an action | Before the action | Remember to call me. |

| Remember to lock | Do not forget to lock it | Future task | Remember to lock the door. |

Why The Verb Form Changes The Meaning
The verb after remember changes the meaning because English uses different verb patterns for different ideas. With to + verb, the action is treated as a task, duty, plan, or reminder. With verb-ing, the action is treated as a memory or experience.
Easy Memory Trick
Remember to looks forward to an action. Remember doing looks back at an action.
Common Mistakes With Remember To And Remember Doing
The most common mistake is using verb-ing when the sentence needs a reminder, or using to + verb when the sentence is about a past memory.
| Incorrect | Correct | Why |
|---|---|---|
| ❌ Remember calling me tonight. | ✅ Remember to call me tonight. | The call is a future task. |
| ❌ I remember to call you yesterday. | ✅ I remember calling you yesterday. | The call happened in the past. |
| ❌ She remembered buying milk, so she went to the store. | ✅ She remembered to buy milk, so she went to the store. | She remembered the task before doing it. |

Remember To Do In Past Tense
Remembered to do means the person did not forget the task. It does not mean the person is remembering a past experience. It means the task was completed because the person remembered it in time.
- I remembered to lock the door. = I did not forget to lock it.
- She remembered to pay the bill. = She paid it because she did not forget.
- They remembered to bring their tickets. = They brought the tickets.
Past tense does not automatically mean remember doing. Ask this instead: was it a completed task or a memory of an experience?
Remember Doing In Negative Sentences
Do not remember doing means you have no memory of a past action. The action may have happened, but you cannot recall it.
- I do not remember saying that.
- She does not remember meeting him before.
- We do not remember receiving your email.
These sentences do not mean the action never happened. They only say that the speaker cannot remember the action.
Remember Not To Vs Not Remember Doing
Remember not to do something is a reminder to avoid an action. Not remember doing something means you have no memory of doing it.

Think of to as pointing forward: remember to send, remember to check, remember to bring. Think of -ing as pointing backward: remember sending, remember checking, remember bringing.
